[Mike Pithouse]

Hi all,

 

Is is possible to set an ath9k-based access point's Modulation scheme
using iw or similar?

 

For example:

 

DSSS or OFDM

64QAM, 16QAM,QPSK,BPSK

 

Thanks in advance, Mike.

Hi Luis,

I have version 0.9.20 of iw (which I thought was the latest) and I don't seem to have a bitrates option.

Is there a more recent version I should be using?

Thanks, Mike.

Just the ticket - thank you.

I see there's currently some 'inactive' code that will allow the same command to be used to set the MCS index.

Do you know when/if this code will be available?  Alternatively, is there another method currently available to set MCS index?

Thanks, Mike.

Johannes, is this a TODO still?

You can only do legacy right now, we don't have the
nl80211/cfg80211/mac80211 infrastructure in place for it at this point.

OK.

Is there any other way to achieve this?  I need to do some testing for each MCS index.  It doesn't need to be elegant!  We can code something up if we have some pointers.

Cheers, Mike.

Hi,

Is anyone able to confirm whether or not it's possible (by any means) to set the MCS Index for an ath9k Access Point?

Thanks, Mike.

Please learn to bottom post:

http://en.wikipedia.org/wiki/Posting_style#Bottom-posting

Then you already had an answer to your question but you keep on
asking. The answer was we need API for this which is not present yet.
If you want to hack something around you can go ahead and try using
debugfs on ath9k.
